On the morning before Jaliyah took her bulletproof backpack to school for the first time, her father, over a bowl of Fruit Loops, had some grown-up explaining to do.

"So if any bad guy was to come in to your classroom, remember we don't use guns, right, but bad guys do, right? So if they were to come in to your classroom with any guns, you put this on and this would stop the bullets," Boykin told his daughter.

While outfitting a kindergartener with body armor may seem way over the top, Boykin said it just reflects "the world we live in."

"[It's] sad in a lot of ways," he said. "We shouldn't have to do these things. But in today's society, if we don't, who knows what tomorrow will look like."

Boykin is among a wave of parents willing to try the extreme and controversial measure of making his children wear bulletproof materials to protect them at school in the wake of the shooting in Newtown, Conn., and other school shootings.

However, gun control advocates see this as a disturbing sign of how willing we have become to accept gun violence as the norm.

"We can accept that when our children go to school, they should be under the same type of threat of active combat as law enforcement and soldiers, or we can make sure that the shooting never starts in the first place by making sure that our gun laws are so strong that people who are homicidal maniacs cannot gain easy access to firearms," said Ladd Everitt, the director of communications for the Coalition to Stop Gun Violence.

Boykin said it is the reality his family is facing firsthand. They live in Aurora, Colo., the site of the movie theater shooting last July that left 12 people dead and 58 injured. He said he used to bring his daughter to that theater regularly and knew people who were inside on the night of the shooting.

"It was the worst day of my life," he said. "I didn't know who was alive and who was dead. I haven't let Jaliyah out of my sight since."

It is that anxiety that has led to an emerging market for something most Americans would have never thought necessary: bulletproof clothing -- from jackets to shirts to backpacks -- made for children.

"I think that there are other ways to protect your child. I just felt like this was the best thing for mine," Boykin said. "It felt like this was the easiest thing that I could do to keep my arm around her when I couldn't keep my arm around her."

Tapping into that urge -- and some critics would say exploiting it -- is a man named Miguel Caballero. His company, based in Bogota, Colombia, designed and manufactured the 3-pound bulletproof backpack Jaliyah now carries to school.

"We are the last resort," Caballero said. "In the moment when all the rest, they are not working, we have the best way to guarantee the life of the child."

Caballero has been making bulletproof products for 20 years. An industry leader in a country plagued by decades of violence, Caballero says he ships to 23 countries around the world and counts 11 sitting presidents, and even actor Steven Seagal, among his clientele.

Miguel Caballero: 'I Am Not The Aggressor'

Caballero is so convinced his product works, he has a longstanding, if not bizarre tradition at the factory for new employees: Fire bullets at them while they wear his products.

Today, his 260 employees are hard at work making bulletproof gear for the American Red Cross, the Paraguayan police and, now, American children -- the company's newest clients.

Caballero said the idea came to him on the fateful day three months ago when 20 first graders were gunned down at Sandy Hook Elementary School. Within days of the shooting, Caballero said he started receiving requests from anxious American parents.

"All the emails from parents say, 'I am afraid to send my child to the school,'" he said.

He bristled at the suggestion that he is exploiting parents' fear.

"I am in the business of personal defense," Caballero said. "I am not the aggressor. I am not the attack people. I only want to supply any solution in the United States."

But gun control advocates say that is ridiculous and companies like Caballero's are taking advantage of parents' panic over their children's safety to turn a profit.

Everitt said companies like Caballero's are part of the problem, not the solution.

"They have a profit motive," he said. "They're businessmen. The goal of a businessman is not to enact laws to ensure public safety."

Everitt, who is also a parent, was skeptical of how effective the backpack would be.

"Are they going to be wearing a bulletproof helmet, as well? Are they going to be covered from head to toe?" he asked. "If a guy walks in there and unloads more than 150 rounds in less than five minutes, how many kids are going to saved by bulletproof clothing in that instance?"

Caballero insisted his products speak for themselves. To demonstrate, he fired eight shots from a 9mm handgun straight into one of his backpacks.

"So, you can see, no penetration," he said.

Caballero would not reveal the secrets of the backpack's technology, but he said the key is a special gel that absorbs the impact of the bullet and disperses the energy.

The National Institute of Justice, the American government agency that certifies bulletproof clothing, said Caballero's material passed bulletproof testing. His first shipment of 150 units was on its way to the U.S. just last month. Last week, the line officially launched here.

But Everitt said these products show we are losing sight of the real issue of gun control in America, and any parents considering putting their kids in body armor to go to school should ask themselves if they want their children to live in a country full of fear of being attacked.

"Does that sound like a vision of America, or does that sound like a third world country?" Everitt said. "This is insane."

But for Boykin, that threat already exists and he wants to take action against it. The early reviews from Jaliyah on her new bulletproof backpack were mixed.

"It's tight, it's heavy and slow," she said, but she noted that she liked "the hearts, stars and fairies" that adorned it.

Now that Jalyiah can potentially protect herself with the backpack, her father said they might start going to the movies again.
